Motorola VME Embedded Control
Motorola MVME162PA-252SE VME Embedded Controller
A single-slot MVME162PA2 configuration combining a 25 MHz MC68040 processor, 32MB SDRAM, SCSI, Ethernet and a dual IndustryPack logic interface.
Product Overview
Embedded processing with local I/O flexibility
The MVME162PA-252SE is the Motorola ordering configuration identified in the MVME162PA2 datasheet as a VME embedded controller with a 25 MHz MC68040 processor, 32MB SDRAM, SCSI and Ethernet.
The board combines processor, memory and VMEbus resources with two single-high IndustryPack positions, or one double-high position, while occupying one VME slot. This structure supports application-specific I/O expansion without changing the board-level processor platform.
Front-panel connectivity includes four serial connectors, a SCSI connector and an Ethernet connector. Selection and installation should follow the Motorola MVME162P2 documentation, particularly for cooling, VMEbus configuration and IndustryPack module loading.

Operating Functions
How the processor, buses and I/O work together
VMEbus data movement
Motorola’s VMEchip2 provides the VMEbus interface, local-to-VME and VME-to-local DMA functions, system-controller support and interprocessor control/status resources. The interface supports D64 and block-transfer operation documented for MVME162PA2.
IndustryPack expansion
The two IndustryPack logic positions accept two single-high modules or one double-high module. Each port has a DMA channel, allowing application-specific I/O to exchange data with local memory.
Peripheral communication
The MVME162PA-252SE ordering configuration includes SCSI and Ethernet. Four EIA-232-D DTE serial ports provide additional front-panel communication through RJ-45 connectors.
Timing and supervision
Six 32-bit timers provide 1 µs resolution. The onboard watchdog can generate a reset on timeout, while MVME162FW supplies boot, monitor and diagnostic functions.
Installation Highlights
Configuration checks before the board enters service
Cooling and slot planning
The official datasheet specifies operation from 0°C to +55°C with forced-air cooling. Confirm airflow with the actual chassis load and any installed IndustryPack modules.
IndustryPack loading
Match the installed IP modules to the documented single-high or double-high arrangement and include their current demand when reviewing system power.
VMEbus configuration
Set the board’s system-controller and arbitration options according to the chassis architecture. The datasheet identifies the system-controller function as jumper-selectable.
Cable and connector matching
Use the documented front-panel connector types: four RJ-45 serial ports, one 68-pin SCSI interface, one DB-15 Ethernet interface and two 50-pin IndustryPack I/O connectors.
